How to Use

1) Prepare Surface

To apply, surface moisture content must be less than 25% as measured with an electronic moisture meter. Surfaces must be free of dirt, grime, efflorescence, lime run, construction debris, form oils and release agents, chalked materials, loose and peeling paint, mold, mildew, etc. All cracks should be pointed or caulked. Do not apply if rain, snow, or temperatures below 40°F are expected within 48 hours. Do not apply if relative humidity is greater than 80%.

2) Apply Chalky Wall Sealer™

Horizontal Surfaces: Spray solution onto surface until product slightly pools.Vertical Surfaces: Spray solution beginning at top of surface working downward in vertical sections. Allow solution to drip heavily and maintain a 6-8 inch rundown from contact point. For areas that dry more rapidly than others, apply a second light coat.
